This bird is somewhat irregularly distributed. In the southern and 
southeastern portions of our state it is quite common from about May 1 
to the middle of September. In Crawford and Erie counties, or in the 
j extreme northwestern part of the commonwealth, Mr. George B. Sennett 
has found it to be a rare summer sojourner. It is reported to be a rather 
common summer resident in central Pennsylvania. I have found them 
to be very common in summer at State College, in Centre county. The 
name Grasshopper Sparrow is given because its note bears a very close 
| resemblance to that of the grasshopper. In Chester and the neighbor- 
i ing counties this bird is a common frequenter of dry sandy meadows, 
clover and grass fields, about which it may often be seen perched on the 
top of low weeds or on posts and fence rails. This is one of the spar¬ 
rows to be seen in the summer time perched on the fences along the 
roadsides. I have never observed a bird of this species in a tree, and it 
rarely is seen to perch on bushes. The nest is built on the ground, and 
! is usually concealed by a tuft of grass or a bunch of weeds. It is com- 
i posed of dry grasses, horse hair and fine roots; eggs, four or five, white 
with reddish-brown spots, .72 length by .61 breadth. 
The Yellow-winged Sparrow, during its residence with us, feeds prin- 
1 cipally on different kinds of insect life ; the small seeds of various plants, 
grasses and weeds are also taken. Beetles, grasshoppers, flies, earth¬ 
worms, etc., are eaten in large numbers; the young, when in charge of 
the parents, are fed chiefly on spiders and larvae.
